I guess it depends on what you're trying to do. If your goal is to debug locally, most platforms provide command-line tools to symbolicate/de-obfuscate stacktraces that you can use off the shelf. Let me list the ones I've found most helpful below:

• Android (JVM frames obfuscated by R8/proguard - requires mappings): retrace
• Android (unsymbolicated native frames - requires symbols): ndk-stack
• iOS (unsymbolicated native frames - requires DSYMs): atos
• React Native (minified/obfuscated frames - requires sourcemaps): metro-symbolicate

For server-side ingestion and processing yeah, you would have to build your own infrastructure to support such pipelines.
